JOHN DILLON, OI NEW/V YORK, N. Y.

LUADING AND UI-TLOADING DEVICE.

Application filed March 3, 1921. Serial No. 449,298.

1 all 107mm if many concern Be it lrnznvn that I, Join? DILLON, a citizen oi? he United States, residing at New York ci in the county New York, State of New l orlr, have invented certain new and useful AiuPiOXPl'llGl'lllS in Loading and Unloading;- Devices; and I do hereby declare the following to he a full, clear, and exact de scription oi the invention, such as will enable others skilled in the e t to which it up pertains to make and use the This invention relates generally to loading and unloading devices, being particularly adoptable tor use in connection with ti ks or railway cars and providing means of simple and improved construction for facilitating he loading and unloading opcrations thereof.

further object of the invention is to pro vide means of the character statedwhich nun be easily and quickly applied to and r moved from the vehicle, and by the use oi" which heavy weights and objects may be easily handled with the exercise of a minimum amount ol physical force.

A still further object is to provide :i device of the char; :ter stated which shall be oi simple cmistruction and composed oi but few ports, the said ports hcinp; o't strong construction and assemblage whereby (longer oi? breelnig'c -or clerungrei'ncnt tl'iereoi is obviated, which is easy of operation, and which may be purchased and nlnintninen at small. cost.

YJith t n is in view, others whiih will il-PGill us the zicscri ition proceeds, the invention consists in the novel construction, combination and ar angement of ports, all "ill he described more fully or. illus. :d in the drawings, and

ticularly pointed out in the claims.

druwings: 1 h is :1 side elevation o? :2. vehicle ol conventional d 'g'n and illustrntii N: the application thereto in :1 loading: and unloadinp' device constructed in uccordunce with the invention.

Figure 2 is n. horimntnl section taken through the Windlass device, illustrating the manner in which the some is constructed and the manner in which a driving connection between. the lever and the drum is estnl lished.

l igure 3 is e de nil View illustrating the Windlass supporting device and the Inf Lilli in which the same is attached to its support.

o her with Referring now more particularly to the drawings, 5 indicates generally the vehicle, the some being :1 conventional design and shown merely for the purpose of illustrating the application of my invention thereto.

The windlnss or elevating device is shown as comprising a wheel, the central portion of which constitutes :1 drum 6 to which a draft cable is to be attached, and the ends of the drum are enlarged so as to provide onnular flanges 7. The drum is rotatably mounted upon a suitable spindle 8 and be tween the spaced bars 9 which constitute a port of the means by which the drum is actuated. The spaced bars are provided at their inner ends with openings as shown to aline with the bore of the drum to receive the spindle 8, said bars extending outwardly from the spindle in spaced parallel relation and are secured at their outer ends to the opposing; sides 0i a handle or lever 10. If desired, the said spaced bars may be provided with longitudinal series of spaced openings 10 in order that the handle or lever 10 may be adjusted.

The bars 9 are provided imvardly from their ends with cars ll, adapted to receive 21 pin 12 passing through suitable openings in the inner ends of the pew]. member T his pawl member is oi sul'istuntizilly llshape, the bight portion of which rests upon the peripheries of the annular "flanges 7 end is adapted to engage with the teeth 14 arranged in spaced. relation upon the spliced ieripheries. lt will be observed that when the lever is moved in one direction the bipght portion of the pawl 13 will engage the teeth 14 and thus lock the lever with the drum, while movement of: the lever in the opposite direction will cause the said pawl to slide or play loosely over the said teeth.

The spindle 8 has an arm 15 rigidly secured thereto and extending}; radially therefrom and to the outer end of this arm is secured a dog 16 to engage with the teeth of a. ratchet wheel 1? secured to the drum. twill be observed that the teeth of this ratchet wheel are disposed to extend in the some di rection as the teeth 14; oi the drum and it is obvious that the pawl 16 will permit the drum to rotate only in one direction.

The spindle 8 is provided at one end with a downwardly extending portion 19 constitilting a, support, and this support is designed to fit into a sleeve 20 secured as at 21 to the side of the vehicle. The support 19 is capable of sliding freely in the sleeve and may have limited rotation therein whereby liberal adjustment of the Windlass device relative to the vehicle body may be made. -The lower end of the support 19 has a locking pin 21 passing therethrough to the cable is provided with a hook 25 to be engaged with a sling, basket, truck or other container constituting a hit. This container indicated at and in the present instance, comprises a truck including'a platform 26 supported upon roilers 2'7, wires, cables or ropes 28 being secured to the ends of the said truck and constituting a sling to be engaged by a hook at the free end of the cable. 7 Assuming that it is desired to load a vehicle with heavy articles,- thesaid articles are placed upon the truck and the latter wheeled to a position directly beneath the free end of the cable. The hook of the latter will be engaged in the sling of the truck, and the pawl member 13 is moved so that the bight portion thereof rests upon the peripheries of the drum flanges. Reciprocating movement then applied to the lever will cause the cable to be wound upon the drum, it being understood that movement oi? the lever in one direction will cause a positive con nection between the lever and the drum to be established, while movement of the'lever in the opposite direction will be unimpeded; the pawl 01 dog 16 holding the drum against retrograde movement while the lever pawl is obtaining a fresh hold. This operation continues until the lift reaches the desired elevation, whereupon the articles thereon may be either removed from the truck and placed in the vehicle or the truck may be rolled upon the floor of the vehicle to that part thereof where it is desired to deposit the articles contained thereon.

Unloading of the vehicle is accomplished by reversing the operation, and in order that the drum may be set free at any time upon its spindle, the dog 16 has a wire 30 attached thereto and disposed within convenient reach of the lever operator. This wire may be actuated to move the pawl into or out of engagement with the ratchet wheel 17 as is obvious.

From the foregoing it is obvious that I have provided mechanism which is fully ca pable of attaining the ends set forth. For purposes of illustration the device is shown.

as used in connection'with the loading and unloading of vehicles, but it will be understood that, the invention is not to be limited to such use. A device of such character is readily adaptable for use in warehouses and other storage places where it is required to lift and transport heavy weights and objects and such functions may be quickly attained by using the device of my invention with the expenditure of but a small amount of physical energy. I also reserve the'right to resort to variations in the structure and assemblage of the parts, as it is obvious that liberal changes of such nature may be resorted to without departing fromthe invenion as defined by the claim.

What is claimed is:

In a device of the class described, a spindle, an angularly disposed support at one end of said spindle, a sleeve to receive and maintain said support, a drum on said spindle, levers pivoted upon said spindle one upon each side of said drum, a handle connecting the outer ends of said levers beyond Said drum, teeth on the periphery of said drum, a U-shape pawl pivoted at its ends to said levers, the bight portion of said pawl adapted to engage the teeth of said drum, a ratchet wheel carried by the drum, a pawl engaged with the teeth of said ratchet wheel, and a cable secured to said drum. In testimonywhereof, I afliX my signature, in the presence of two witnesses.
